Accessory Kits Description Suggested and Required Use

1. Disconnect Kit

The kit is used to disconnect electrical power to the fan coil so service or maintenance may be performed safely.SUGGESTED USE: All (Consult local code).

2. Downflow Base Kit

This kit is designed to provide a 1-in. minimum clearance between unit discharge plenum, ductwork, and combustible materials. It also provides a gap freeseal with the floor.

REQUIRED USE: This kit can be used whenever fan coils are used in downflow applications and local code requires a metal base for the unit.

3. Downflow Conversion Kit

Fan coils are shipped from the factory for upflow or horizontal-left applications. Downflow conversion kits provide proper condensate water drainage andsupport for the coil when used in downflow applications. Separate kits are available for slope coils and A-coils.

REQUIRED USE: This kit must be used whenever fan coils are used in downflow applications.

4. Fan Coil Filter

The kit consists of 12 fan coil f ramed filters. These filters collect large dust particles from the return air entering the fan coil and prevents them fromcollecting on the coil. This process helps to keep the coil clean, which increases heat transfer and in turn the efficiency of the system.

SUGGESTED USE: To replace filters in FX4C fan coils.

5. Condensate Drain Trap Kit

This kit consists of 50 PVC condensate traps. Each trap is pre-formed and ready for field installation. This deep trap helps the system make and holdproper condensate flow even during blower initiation.

SUGGESTED USE: All FX4C fan coils.

6. Downflow/Horizontal Conversion Gasket KitThis kit provides the proper gasketing of units when applied in either a Downflow or Horizontal application.

ESTIMATED SOUND POWER LEVEL FOR FX4C FAN COILS*

METHOD: Estimated Fan Sound Power (in decibels 10E-12 watts) is calculated in accordance with procedure described in ASHRAE 1987HVAC ‘‘Systems and Applications Handbook,’’ Chapter 52, ‘‘Sound and Vibration Control,’’ using the ‘‘Specific Sound PowerLevel’’ approach.

ACCURACY: This is a prediction method, based on an accepted method which has demonstrated satisfactory results in field applications.However, field test results may generate sound pressure values which differ from these predicted values, as the current stateof the art in determining sound power varies in accuracy from 0.2 db in mid-range (250 to 4000 Hz bands) to 3 to 4 db in 125and 8000 Hz bands and up to 6 to 8 db in 63 Hz band.

MINOR CHANGES: Use for estimating sound power at other conditions of airflow and external static pressure.
